从 environment.yml 文件创建环境 tqdm 访问被拒绝

Question

我正在尝试在管理员命令提示符下通过运行 conda env create -f environment.yml 从 environment.yml 文件创建环境。 environment.yml 文件如下：

name: pytorch0.4
channels:
  - pytorch
  - defaults
dependencies:
  - python=3.6.5
  - pytorch=0.4.1
  - torchvision
  - numpy
  - nltk
  - ipython
  - docopt
  - pip
  - pip:
    - tqdm

执行运行命令后，出现了这个错误：

CondaEnvException: Pip failed

我认为我的环境创建不正确，因为我无法在环境中使用依赖项或激活它。我还尝试通过运行 pip install tqdm --user 安装 tqdm，它说 Requirement already satisfied: tqdm in c:\users\pc\appdata\roaming\python\python38\site-packages (4.58.0)。那我该如何启动那个环境呢？

Conda 应该能够在不求助于 pip 的情况下解决这个问题，因为 tdqm 在 defaults 频道上可用。此外，nltk 具有 tdqm 作为依赖项，因此 YAML 可以简化为

文件：pytorch0.4.yaml

name: pytorch0.4
channels:
  - pytorch
  - defaults
dependencies:
  - python=3.6.5
  - pytorch=0.4.1
  - torchvision
  - numpy
  - nltk
  - ipython
  - docopt
  - pip

此外，虽然在 Conda 环境中使用 pip 是有效的，但 it comes with some caveats。其中之一是永远不要使用 --user 标志，因为这最终会将包放置在环境 site-packages 之外，并可能导致违反 Conda 如此热衷于建立的环境隔离。
